2017~2025 HELP!! Replaced Lower Arm is different from Original

I own a 2021 CE AWD(non-turbo). I had to replace the rear wheel and suspension due to a bad T'bone collusion. I think my original part number is probably KD35-28-300 and the replacement is probably KD35-28-300A(This was mentioned by the repair shop before the replacement).

The official mazda part mentions both parts but some parts store mentions that KD35-28-300A is not for AWD. The replaced part looks a little different from the original. please check the highlighted image that has mounting brackets(Maybe?). I want to make sure they used the right part.
